I realised recently that my life would be a lot better right now if I worked the so-called soul destroying corporate job because I'd have more money, work fewer hours, have less stress during work, people would expect less from me, I'd have infinitely more holidays, more work-free weekends...
Sometimes its hard to see what you've got until its gone :)
Don't get me wrong, I like being a founder and don't regret it for a minute, but when times get tough I look back and think the soul destroying corporate days were actually pretty good.
Which brings me to this: Life (usually) really is what you make of it.
